Why would there vertical lines on my toshiba theater wide tv?


this sounds like a bad capacitor. If you want to fix it yourself and know how to solder on a pcb, then replace all of the electrolytic capacitors.

Vertical lines on lcd toshiba tv


I'm sorry that the TV is displaying vertical lines on the screen. Please follow the troubleshooting steps and check the operation:

Please make sure that the connections are secure and proper.
Try connecting a different video source like DVD player or VCR and check the operation. If it works with another device, the issue might be with the input device currently.
Also try connecting the device to a different port in the TV if no other devices are available.
If the issue persists, try with a different cable.
Perform a power resetting and check the operation. To perform the power resetting, unplug the TV from wall outlet for more than 2 minutes and then reconnect it.
If the issue persists, after all above troubleshooting steps, service may be required. You can click hear to setup a service for the TV.

Also it would be good if you can come back with the model # of the TV to check whether the issue can be resolved with a firmware update.
Thanks for understanding. Please let me know if you require any clarifications/additional help.

2/5 of the screen has vertical lines multi colors. Is this a fixable problem?


My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display problem (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.

Most likely it is the flat panel tab bond failure (panel made by Samsung). Further resolution updates will be on my Facebook page.

MY toshiba tv MW27F11C only shows a white line when turned on


Hello uuka,

You have vertical collapse. This is most often caused by a defective vertical output integrated circuit, an open dropping resistor which feeds the supply voltage to the I.C., one or more defective electrolytic capacitors in the vertical circuit or something as simple as bad solder connections. The latter will usually manifest itself as an intermittent failure. Less likely, but stilla possibility is a defective yoke, but this a rare.

Unless you are handy with a soldering iron and have some experience this is definitely something I suggest that you refer to a qualified technician. Depending on the actual cure for the problem, this would typically be under $100 in my shop, but we are in a small town and prices are cheap. I would definitely recommend a repair on this since it can not be replaced. They don't make a TV/DVD/VCR combination any longer and the picture quality on these Toshiba/Orion combos has been very good over time.

Hope this helped and don't forget to rate...
Thanks!
